Information in neuronal networks may be represented by the spatiotemporal patterns of spikes. Here we examined the temporal coordination of pyramidal cell spikes in the rat hippocampus during slow-wave sleep. In addition, rats were trained to run in a defined position in space (running wheel) to activate a selected group of pyramidal cells. A template-matching method and a joint probability map method were used for sequence search. Repeating spike sequences in excess of chance occurrence were…

Different propagation speeds of recalled sequences in plastic spiking neural networks

This analysis theoretically analyze sequential activity learning and retrieval in a recurrent neural network with realistic synaptic short-term dynamics and STDP and suggests that a multiplicative STDP rule with dominant NN spike interaction might be implemented in V1 since recall speed was almost constant in an NMDA-dominant regime.

Precisely repeating spike temporal sequences in spontaneous activity of cultured hippocampal neuronal networks on multi-electrode arrays

It is demonstrated that intricate patterns of precisely temporal structures are one of the main forms of temporal coding, and may encode information even during spontaneous activity, in hippocampal neurons from rats cultured on a multi-microelectrode arrays dish.

Detection and Evaluation of Spatio-Temporal Spike Patterns in Massively Parallel Spike Train Data with SPADE

A novel method capable of overcoming the computational and statistical limits of existing analysis techniques in detecting repeating STPs within massively parallel spike trains (MPST) is introduced and two alternative approaches to distinguish statistically significant patterns from chance sequences are introduced.

Replay of cortical spiking sequences during human memory retrieval

R ripple oscillations in the human cortex reflect underlying bursts of single-unit spiking activity that are organized into memory-specific sequences, demonstrating that human episodic memory is encoded by specific sequences of neural activity and that memory recall involves reinstating this temporal order of activity.

Replay of memories of extended behavior in the rat hippocampus

A probabilistic neural decoding approach is developed that allows to show that firing sequences corresponding to long runs through a large environment are replayed with high fidelity (in both forward and reverse order), and suggests that extended replay is composed of chains of shorter subsequences, which may reflect a strategy for the storage and flexible expression of memories of prolonged experience.

Spike sequences and their consequences

Characterizing hippocampal replay using hybrid point process state space models

A hybrid state space framework is introduced to describe the richness of replay sequences and shows how defining discrete latent states associated with continuous latent dynamics and point process observations allows us to identify when non-local replay sequences occur, categorize the type of sequence based on their inferred continuous dynamics, and decode the spatial trajectory corresponding to the replay sequence.

Perisomatic-targeting interneurons control the initiation of hippocampal population bursts

This experiment showed that induced spiking activity of an individual perisomatic-targeting interneuron can both suppress and subsequently enhance local sharp wave generation, suggesting that interneurons may play an integral part in the local information processing that takes place in the hippocampus.

Local generation of multineuronal spike sequences in the hippocampal CA1 region

It is shown that optogenetic activation of a small group of CA1 pyramidal cells in mouse hippocampus yields consistent multineuronal spike sequences, and that their sequential firing order is similar to that observed during spontaneous “ripple” and theta oscillations, suggesting participation of single neurons and their sequential order in population events are not strictly determined by extrinsic inputs but also influenced by local-circuit properties.

Propagation of Spike Sequences in Neural Networks

This work analytically and numerically investigates the propagation of 2-composite waves, i.e., two-spike sequence propagation, using the simplest synaptic architecture that supports composite waves, a three nearest-neighbor coupling feedforward network.



Reactivation of Hippocampal Cell Assemblies: Effects of Behavioral State, Experience, and EEG Dynamics

Pattern reinstatement was strongest during sharp wave–ripple oscillations, suggesting that these events may reflect system convergence onto attractor states corresponding to previous experiences, and do not necessarily reflect persistence of an active memory.

Spatiotemporal firing patterns in the frontal cortex of behaving monkeys.

Spatiotemporal firing patterns revealed by a method that detects all excessively repeating patterns regardless of their complexity or single-unit composition suggest that the patterns were generated by reverberations in a synfire mode within self-exciting cell assemblies.

Spike synchronization and rate modulation differentially involved in motor cortical function.

Findings indicate that internally generated synchronization of individual spike discharges may subserve the cortical organization of cognitive motor processes.

Phase relationship between hippocampal place units and the EEG theta rhythm

The phase was highly correlated with spatial location and less well correlated with temporal aspects of behavior, such as the time after place field entry, and the characteristics of the phase shift constrain the models that define the construction of place fields.

A Statistical Paradigm for Neural Spike Train Decoding Applied to Position Prediction from Ensemble Firing Patterns of Rat Hippocampal Place Cells

The statistical paradigm provides a reliable approach for quantifying the spatial information in the ensemble place cell firing patterns and defines a generally applicable framework for studying information encoding in neural systems.

Theta phase precession in hippocampal neuronal populations and the compression of temporal sequences

Large‐scale parallel recordings are made use of to clarify and extend the finding that a cell's spike activity advances to earlier phases of the theta cycle as the rat passes through the cell's place field, and to show Granule cells of the fascia dentata are also modulated by theta.

High-Frequency Oscillations in the Output Networks of the Hippocampal–Entorhinal Axis of the Freely Behaving Rat

There is a powerful synchronization among the neuronal networks that connect the hippocampus to the neocortex during each hippocampal sharp wave, which biologically constrains theoretical models of hippocampal function and dysfunction and has the capacity to support an “off-line” memory consolidation process.

The findings suggest that neuronal activity of hippocampal place cells in the awake states may influence the firing characteristics of these cells in subsequent sleep episodes, and increased firing rates along with the greater number of multiple spike bursts and the shorter interspike intervals within the burst, following exposure to a cell's place field, may represent possible information processing during sleep.

Dentate EEG spikes and associated interneuronal population bursts in the hippocampal hilar region of the rat.

It is suggested that dentate spike-associated synchronized bursts of hilar-region interneurons provide a suppressive effect on the excitability of the CA3-CA1 network in the intact brain.

Replay of Neuronal Firing Sequences in Rat Hippocampus During Sleep Following Spatial Experience

The correlated activity of rat hippocampal pyramidal cells during sleep reflects the activity of those cells during earlier spatial exploration and this memory for temporal order of neuronal firing could be produced by an interaction between the temporal integration properties of long-term potentiation and the phase shifting of spike activity with respect to the hippocampal theta rhythm.
